Folks have been complaining that our scrolling on iOS and other touch-based platforms is slow. Especially on listview pages.

After poking around, it looks like the slow down is caused by the framework registering touch event handlers on the document.

Simply doing this:

is enough to slow down scrolling performance in a long document with static markup and no other JS. We need to figure out if we can re-work our event handling so that we don't have to listen for touch events at the document level.
